Percentage of apoptotic index in the cell groups incubated for 12 h (n = 6 in each experiment). Shiny DAPI-positive cells were quantified in the various experimental groups. Cells present in 6 high-powered fields (HPF; Magnification ×20) were counted in each experiment and the ratio of apoptotic cells was calculated as the percentage of the whole cell number. Values were mean ± SD. Statistical analysis was performed by one-way analysis of variance with all pairwise multiple comparison procedures done by Dunn’s test. *Values significantly different from control groups in the BT-20 and MDA-MB-231 cells (P < 0.01). **Values significantly different from the 200 nM GA group in the BT-20 cells (P < 0.01). #Values significantly different from the 400 nM and 800 nM GA groups in the BT-20 cells (P < 0.001). +Values significantly different from the 200 nM and 800 nM GA groups in the BT-20 and MDA-MB-231 cells (P < 0.001).
